Reflectin is a protein originating from the Hawaiian Bobtail Squid, Euprymna scolopes, which is native to the central Pacific Ocean. Reflectins, a recently identified protein family that is enriched in aromatic and sulphur-containing amino acids, are used by certain cephalopods to manage and manipulate incident light in their environment.[citation needed] It is possible that reflectins are beta barrel proteins.
